I thought it might be easier if people posted what groups they'd like to get together and what members they already have so that, if people want to join a group, they know what is already being worked on. I can keep this first post updated as long as people let me know when changes need to be made. Also, if there are cosplays you'd like to have in the group but don't have anyone cosplaying them yet, you may include those.

Also, I should have reserved two or three other posts. o_o The first one is going to get long. If you're looking for a particular group, it's probably fastest to search the page using your browser (Ctrl + F on most Windows browsers, I think it's Command + F on Macs) and type in the series name you're looking for.

I'm not sure what my cosplay plans will be for A-Kon24 but I'm currently working on my Mako cosplay so I'll more than likely bring him. And I'm debating on whether to work on Neku Sakuraba or Jack Spicer next.
